Description

L'invention est relative à un chariot à niât télescopique, du type comportant un châssis automoteur à quatre roues, ledit châssis portant une cabine contenant un poste de conduite et un groupe motopropulseur, ledit groupe motopropulseur étant protégé par un capot portant le siège du conducteur et ledit capot étant rabattable vers l'arrière à partir d'une position de fermeture du capot protégeant le groupe motopropulseur jusqu'à une position d'ouverture du capot donnant accès au groupe motopropulseur.The invention relates to a telescopic trolley, of the type comprising a four-wheel self-propelled chassis, said chassis carrying a cabin containing a cockpit and a powertrain, said powertrain being protected by a cover carrying the driver's seat and said cover being foldable towards the rear from a cover closing position protecting the group powertrain to a hood open position giving access to the group powertrain.

On connaít des chariots automoteurs à mât télescopique de ce type, dans lesquels la cabine présente à l'arrière une surface vitrée comportant une partie supérieure fixe portant un essuie-glace et une partie inférieure coulissante apte à être relevée vers le haut. Pour permettre l'ouverture du capot de protection du groupe motopropulseur, on fait coulisser la partie inférieure vers le haut par une opération analogue à l'ouverture d'une fenêtre à guillotine, on déplace le siège de conducteur dans une position prédéterminée pour permettre le passage à travers l'ouverture inférieure et on relève le capot du conducteur. Il est ainsi nécessaire au conducteur de déplacer son siège pour permettre l'ouverture du capot du groupe motopropulseur. En outre, ce chariot de type connu présente également les inconvénients suivants : la surface arrière nettoyée par l'essuie-glace fixé en partie supérieure est inférieure au quart de la surface totale vitrée, et le passage correspondant à l'ouverture inférieure interdit d'installer des sièges avec appui-tête ou dossier surélevé.We know self-propelled trolleys with telescopic mast of this type, in which the cabin has at the rear a glazed surface comprising a part fixed upper carrying a wiper and a sliding lower part adapted to be raised up. To allow the opening of the group's protective cover powertrain, the lower part is slid up by an operation similar to opening a sash window, the driver's seat is moved in a predetermined position to allow passage through the opening lower and the driver's hood is raised. It is therefore necessary for the driver to move its seat to allow the powertrain cover to open. In in addition, this known type of carriage also has the following drawbacks: rear surface cleaned by the wiper attached at the top is less than quarter of the total glazed area, and the passage corresponding to the lower opening it is forbidden to install seats with a raised headrest or backrest.

L'invention a pour but de remédier aux inconvénients précités, en fournissant un nouveau chariot à mât télescopique avec une visibilité arrière améliorée et une possibilité d'accès au groupe motopropulseur sans nécessiter de déplacement du siège du conducteur.The invention aims to remedy the aforementioned drawbacks, by providing a new telescopic mast cart with improved rear visibility and a possibility of access to the powertrain without having to move the seat of the driver.

L'invention sera mieux comprise grâce à la description qui va suivre donnée à titre d'exemple non limitatif en référence aux dessins annexés dans lesquels:The invention will be better understood thanks to the description which will follow given to by way of nonlimiting example with reference to the appended drawings in which:

La figure 1 représente schématiquement une vue en élévation latérale avec arrachement partiel d'un chariot selon l'invention en position fermée de la cabine.Figure 1 schematically shows a side elevation view with partial removal of a trolley according to the invention in the closed position of the cabin.

La figure 2 représente schématiquement une vue en élévation latérale avec arrachement partiel d'un chariot selon l'invention en position ouverte de la cabine, avec basculement du capot de protection du groupe motopropulseur vers l'arrière. Figure 2 schematically shows a side elevation view with partial removal of a trolley according to the invention in the open position of the cabin, with tilting of the powertrain protective cover to the rear.

La figure 3 représente schématiquement une vue agrandie en coupe par un plan médian longitudinal d'une cabine de chariot selon l'invention, illustrant la cinématique d'un mouvement de hayon.FIG. 3 schematically represents an enlarged view in section through a longitudinal median plane of a trolley cabin according to the invention, illustrating the kinematics of a tailgate movement.

La figure 4 représente une vue partielle en perspective arrière d'un chariot selon l'invention.Figure 4 shows a partial rear perspective view of a carriage according to the invention.

En référence aux figures 1 à 4, les chiffres de référence identiques désignent des éléments identiques ou fonctionnellement équivalents.With reference to FIGS. 1 to 4, the identical reference numbers denote identical or functionally equivalent elements.

Sur les figures 1 et 2, le chariot selon l'invention comporte un mât télescopique 1 portant des fourches de chargement. Le mât télescopique 1 est monté solidaire et inclinable par rapport à un châssis 2 automoteur à quatre roues 3. Le châssis 2 porte une cabine 4 contenant un poste de conduite 5 et un groupe motopropulseur 6. Le groupe motopropulseur 6 est protégé par un capot 7 portant le siège 8 du conducteur.In Figures 1 and 2, the carriage according to the invention comprises a mast telescopic 1 carrying loading forks. Telescopic mast 1 is mounted integral and tiltable with respect to a self-propelled chassis 2 with four wheels 3. The chassis 2 carries a cabin 4 containing a driving position 5 and a group powertrain 6. The powertrain 6 is protected by a cover 7 carrying the driver's seat 8.

On entend par groupe motopropulseur tout moyen de création d'énergie mécanique ou hydraulique propre à transmettre un mouvement aux roues et à actionner les actionneurs et éléments de préhension de l'ensemble du mât télescopique 1, notamment les groupes motopropulseurs comprenant un moteur thermique et les groupes motopropulseurs à fonctionnement électrique alimentés par batteries.By powertrain is meant any means of creating energy mechanical or hydraulic suitable for transmitting movement to the wheels and actuate the actuators and gripping elements of the entire mast telescopic 1, in particular powertrains comprising a motor and electrically powered powertrains powered by batteries.

Sur la figure 1, le capot 7 est dans une position de fermeture protégeant le groupe motopropulseur 6 et le siège 8 du conducteur monté sur le capot 7 est dans une position correspondant à la conduite du chariot par un opérateur.In FIG. 1, the cover 7 is in a closed position protecting the powertrain 6 and the driver's seat 8 mounted on the hood 7 is in a position corresponding to the driving of the carriage by an operator.

Sur la figure 2, le capot est rabattu vers l'arrière jusqu'à une position d'ouverture du capot donnant accès au groupe motopropulseur. Dans cette position d'ouverture du capot dans le sens de la flèche 9, le siège 8 du conducteur monté sur le capot 7 passe librement à travers une ouverture arrière de la cabine 4.In Figure 2, the cover is folded back to a position hood opening giving access to the powertrain. In this position opening the hood in the direction of arrow 9, the driver's seat 8 mounted on the cover 7 passes freely through a rear opening of the cabin 4.

A cet effet, selon l'invention, la cabine 4 comporte un hayon arrière 10 relevable vers le haut et déplaçable entre la position fermée de la cabine correspondant à la figure 1 et la position ouverte de la cabine correspondant à la figure 2. To this end, according to the invention, the cabin 4 includes a tailgate 10 can be lifted up and moved between the closed position of the cab corresponding to Figure 1 and the open position of the cabin corresponding to the figure 2.

Dans la position ouverte de la cabine 4, la majeure partie du hayon 10 est escamotée à l'intérieur de la cabine, ce qui présente l'avantage de protéger la surface extérieure du hayon 10 des chocs et des projections indésirables.In the open position of cabin 4, most of the tailgate 10 is retracted inside the cabin, which has the advantage of protecting the surface exterior of the tailgate 10 unwanted impacts and projections.

Pour commander le déplacement du hayon et en assurer l'ouverture automatique à partir d'une position entrouverte, le hayon 10 est monté sur un moyen 11 formant bielle d'articulation et commandé par un actionneur 12. La bielle 11 est articulée en 13 au coin supérieur arrière de la cabine et en 14 sur une patte solidaire du hayon.To control the movement of the tailgate and ensure its opening automatic from a ajar position, the tailgate 10 is mounted on a means 11 forming an articulation connecting rod and controlled by an actuator 12. The connecting rod 11 is articulated at 13 at the upper rear corner of the cabin and at 14 on a fixed leg tailgate.

L'actionneur 12 est articulé en 15 sur la structure de la cabine 4 et en 16 sur une patte solidaire de la bielle 11.The actuator 12 is articulated at 15 on the structure of the cabin 4 and at 16 on a lug secured to the connecting rod 11.

Sur la figure 3, le hayon 10a est représenté en position fermée de la cabine, et est appliqué contre le bord de la cabine 4 par l'actionneur 12a. A cet effet, l'actionneur 12a est monté précontraint dans la position de fermeture du hayon 10a de manière à empêcher toute ouverture intempestive du hayon 10a et à assurer l'étanchéité arrière de la cabine 4.In FIG. 3, the tailgate 10a is shown in the closed position of the cabin, and is applied against the edge of the cabin 4 by the actuator 12a. To this end, the actuator 12a is mounted prestressed in the closed position of the tailgate 10a so as to prevent any untimely opening of the tailgate 10a and to ensure rear cabin seal 4.

Dans la position représentée en traits interrompus, le hayon 10b est représenté en position ouverte de la cabine 4, et l'actionneur 12b est détendu à sa longueur maximale pour relever la bielle 11b vers le haut.In the position shown in broken lines, the tailgate 10b is shown in the open position of the cabin 4, and the actuator 12b is relaxed to its length maximum to raise the rod 11b upwards.

Le hayon 10 porte de préférence en partie inférieure deux roulettes 17 ou galets de guidage aptes à se déplacer dans des glissières 18 solidaires de la cabine 4 au cours du mouvement du hayon. L'extrémité inférieure du hayon est ainsi guidée selon un mouvement de translation, tandis que la partie supérieure du hayon décrit un mouvement de pivotement au cours de l'ouverture. De préférence, les roulettes 17 sont fixées dans une partie de transition correspondant à la prolongation d'un cadre 19 contenant une surface vitrée 20. Le déplacement du hayon 10 s'effectue de manière que la surface vitrée 20 soit entièrement contenue dans la cabine 4 au cours du mouvement du hayon 10.The tailgate 10 preferably carries two rollers 17 or guide rollers able to move in slides 18 integral with the cabin 4 during the tailgate movement. The lower end of the tailgate is thus guided in a translational movement, while the upper part of the tailgate describes a pivoting movement during opening. Preferably, the rollers 17 are fixed in a transition part corresponding to the extension of a frame 19 containing a glazed surface 20. The displacement of the tailgate 10 is carried out so that the glass surface 20 is entirely contained in the cabin 4 during tailgate movement 10.

Dans la position fermée de la cabine, les roulettes 17 sont dans la position 17a tandis que, dans la position ouverte de la cabine, les roulettes 17 sont dans la position 17b. In the closed position of the cabin, the rollers 17 are in position 17a while, in the open position of the cabin, the rollers 17 are in the position 17b.

Sur la figure 4, la surface vitrée 20 est sensiblement carrée et porte un essuie-glace 21 monté en 22 dans le coin inférieur droit de la surface vitrée 20. La longueur de l'essuie-glace 21 est voisine de la longueur du côté de la surface vitrée 20. Pour débloquer le hayon 10 en début d'ouverture et permettre le déploiement automatique de l'actionneur 12, on prévoit avantageusement une poignée de traction 23 et on utilise de préférence comme actionneur 12 un vérin pneumatique ou " vérin à gaz " qui se déploie automatiquement après déblocage du hayon 10.In Figure 4, the glass surface 20 is substantially square and carries a wiper 21 mounted at 22 in the lower right corner of the glass surface 20. The length of the wiper 21 is close to the length of the side of the glazed surface 20. For unlock tailgate 10 at the start of opening and allow automatic deployment of the actuator 12, a pull handle 23 is advantageously provided and preferably uses as actuator 12 a pneumatic cylinder or "gas cylinder" which deploys automatically after unlocking the tailgate 10.

On prévoit avantageusement de munir le hayon 10 d'un joint d'étanchéité 24. Le joint d'étanchéité 24 est un joint périphérique qui est adjacent en 24a au côté supérieur du cadre 19 entourant la surface vitrée, adjacent en 24b aux deux côtés latéraux du cadre 19 entourant la surface vitrée 20 et qui s'étend ensuite intérieurement en 24c sur le prolongement métallique du cadre 19 et est ensuite positionné en 24d en bout de la partie inférieure du hayon 10. De cette manière, l'étanchéité en partie inférieure est réalisée sur le côté extérieur de la cabine en position inférieure sur la trace en traits interrompus 25a, et sur la surface horizontale du châssis 2 automoteur sur la trace en traits interrompus 25b.Advantageously, provision is made to provide the tailgate 10 with a seal 24. The seal 24 is a peripheral seal which is adjacent at 24a to the side upper part of frame 19 surrounding the glass surface, adjacent at 24b to both sides sides of the frame 19 surrounding the glass surface 20 and which then extends internally in 24c on the metal extension of the frame 19 and is then positioned at 24d at the end of the lower part of the tailgate 10. In this way, the lower part is sealed on the outside of the cabin lower position on the broken line trace 25a, and on the horizontal surface of chassis 2 self-propelled on the dashed line 25b.

Le fait de réaliser l'étanchéité intérieurement à la cabine en partie supérieure et extérieurement à la cabine en partie inférieure assure une parfaite étanchéité et élimine tout frottement nuisible au déblocage du hayon 10 au moyen de la poignée de traction 23.The fact of sealing inside the cabin at the top and outside the cabin in the lower part ensures a perfect seal and eliminates any friction detrimental to the unlocking of the tailgate 10 by means of the handle 23.

L'invention décrite en référence à un mode de réalisation particulier n'y est nullement limitée mais couvre au contraire toute modification de forme et toute variante de réalisation dans le cadre et l'esprit de l'invention.The invention described with reference to a particular embodiment is not there in no way limited but on the contrary covers any modification of form and any variant embodiment within the scope and spirit of the invention.
